A number of users have reported problems using the Touch ID fingerprint scanner in the iPhone 5s, and Macworld’s Serenity Caldwell offers some tips on reducing frustration. In particular, she advises scanning your fingerprint at the same angle that you’d most likely use to unlock the iPhone, and if that’s not enough, adding multiple scans at different angles. She also explains some situations where Touch ID might not work well, if at all. follow link
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
